| Mirena IUD | Mirena is a small “T - shaped” contraceptive device, which is made of flexible plastic and is to be inserted by a doctor or nurse. This kind of IUD releases small amounts of progestin continuously during a long period (up to eight years), and thus helps to prevent an unplanned pregnancy.
How Mirena Works
Mirena helps the sperm prevention from joining with an egg by affecting its movement, in other words its work is to  interfere the movement of the sperm to the egg. Mirena contains some kind of hormonal component, which makes this IUD more effective than the ParaGard.
Mirena starts working immediately, if you have it inserted within seven days after the beginning of your period. In case if you have Mirena inserted at any other day of your cycle, you should better use another method of contraception during the first week after the insertion of Mirena, because it begins to provide the protection against unplanned pregnancy after seven days.
